I was just wondering- When using Minix on the ST, would it still be
possible to access the ROM functions in the ST for GEM, etc. ? If so,
I wouldn't think it would be too hard to write some sort of window
system like SunView(tm) so that you could have multiple shells in
multiple windows.
I don't even have an ST yet (I still have my 7 year old 800). But when
I do get one, I was thinking that this would be a fun first project
to work on (if it's possible).

I had basically put off getting an ST (I have a 130XE) but with Minix/ST announced, I have renewed interest. But it would be far more useful with a SunView/X/News/Whatever type of environment. (I assume Minix/ST does not have one yet. Yes/No?) Sounds like a fun project to me also. Daryl Monge UUCP: ...!att!ihcae!daryl AT&T CIS: 72717,65 Bell Labs, Naperville, Ill AT&T 312-979-3603

Porting X to MINIX could be an interesting project. Since MINIX now has amoeba RPC, we could write an IPC interface to X server IPC routines (and client IPC library calls) to handle communication between client and server. I haven't looked at amoeba stuff yet but according to AST it's one of the fastest RPC's around, so it should be interesting to find out the performance of the server- client communication (compared to Sun using TCP/IP). Some extra work is needed in finding an ethernet board for ATARI-ST (is there such a thing?) and writing a device driver for it. Also, the version 11 X server has a very portable porting layer for either mono or color frame buffer displays, so ATARI-ST running MINIX may be a perfect X server station. I don't have an ATARI-ST, but the same can be done on a PC (perhaps easily using already provide Western Digital driver) using EGA/CGA/HGA display. One concern: the size of X server is fairly big, which doesn't go along well with MINIX philosophy (or the compiler and kernel itself). I heard that someone has ported GNU CC to MINIX-ST. How is it working? Can you compile and run a significantly large program (say, about 600K size excutables?) on MINIX-ST (with added memory)? /hjb -- Hwa Jin Bae bae@tis.llnl.gov (Internet) UniSoft bae@unisoft.UniSoft (smail uucp) Emeryville, CA ...!uunet!unisoft!bae (plain uucp) Don't follow leaders; watch the parking meters.

In short, for small RPCs, Amoeba is 9 times faster than the SUN and for large ones, it has triple the bandwidth. Furthermore, the MINIX implementation of Amoeba is in some ways better than the SUN implementation of Amoeba. Andy Tanenbaum (ast@cs.vu.nl)
